ON A DAY IN EARLY 1987, a man who worked for the Nasdaq stock market - let's call him Jones - showed up in the lobby of the World Trade Center. He found the appropriate elevator bank for his floor and pressed the up button. He was making a routine visit to one of the Nasdaq's fastest-growing customers.

Thomas Peterffy 's blues eyes warmly greeted Jones.

Consumer review site Viewpoints lets members offer their opinion on nearly anything. It turns out the site's most active critic is the founder and chief executive. Matt Moog, who launched Viewpoints in 2007 and is regarded as an elder statesman of Chicago's blooming digital startup scene, led his company through a period of self-reflection and change over the last year. The result is a significant overhaul of Viewpoints' technology platform, design and the way its members interact with the site.

After a yearslong turnaround effort, Sara Lee Corp. had just announced better-than-expected results Thursday morning when an analyst on the conference call asked why the stock was going down anyway. "I cannot explain for the life of me why our shares would be down 3 percent right now," replied Brenda Barnes, chief executive of the Downers Grove-based food company.

Q. Read the letter about headlights (Motormouth, Dec. 16, 2007), which got me wondering whether there any rules about the number of lights that can be lit at any time?

They are also, in some cases, much lower than the 22 inches you mention. These fog lights should be turned off when they aren't necessary.

(Reuters) - A mysterious trading pattern noticed on Thursday in the shares of four blue-chip stocks was likely an experiment in the automated hedging of large options positions, an analyst at JPMorgan said. Many investors on Thursday were puzzled by the price action of Coca Cola , International Business Machines , McDonald's Corp and Apple Inc , said JPMorgan Securities derivatives strategist Marko Kolanovic. The prices of the four stocks oscillated in an almost perfect pattern, going up and down at almost exactly the half-hour and full-hour marks, he said.

Want to make your Little Leaguers' summer? Take them on the ultimate roadtrip by visiting all 30 Major League Baseball stadiums in 30 days using Slate's clever ballpark road trip calculator as a guide.

(Reuters) - Shares of Demand Media Inc plunged 20 percent in Tuesday morning trading after the company trimmed its second-quarter revenue forecast and withdrew its 2013 estimates, prompting two researchers to downgrade the company's stock. Demand Media on Monday lowered its second-quarter forecast, blaming a reduction in search engine referral traffic and it announced the acquisition of an e-commerce platform Society6. Demand Media, which owns websites eHow, Livestrong and Cracked, has been dogged in recent years by the changes Google made to its search engine algorithm.
